The National Pollutant Discharge Elimination System (NPDES) is perhaps the most important environmental regulations on the books. NPDES regulates discharges of stormwater from land development activities and is the reason you see silt fence around construction sites and retention ponds associated with commercial developments. Stormwater treatment facilities often include engineered wetlands and deploy aquatic vegetation to improve water quality. While these systems are designed by civil engineers, Biome’s Professional Wetland Scientists often cooperate in design and construction of a stormwater system. Permitting of stormwater facilities is often conjoined to wetland permitting.
